Mechanical Fan Sets

Product Descriptions

SE Controls’ SHEVTEC range of fans are designed to extract hot gases from corridors and lobbies via smoke shafts. All fan sets are tested to European Standard EN12101-3 and installed as part of a fire engineered solution. There are advantages in using mechanical smoke shafts over code compliant natural ventilation shafts, namely: the shaft sizes are generally smaller than ADB compliant shafts (typically 0.6m2 vs 1.5m2). Furthermore the fan sets allow greater efficiency in achieving necessary pressure differences thereby allowing increased escape travel distances and reducing the reliance of multiple stair cores.
